Anti-Wobble Block Assembly 4.5mm Tubing

What Our Gearhead® Experts Are Saying:

"I run this on a BackStage carrying race builds that I cannot afford to have shifting around in transit, and the ball bearing integration into the hitch tube removes every trace of the lateral movement that was there before. High-strength steel construction means it is not something I will ever need to think about again, which is exactly the standard a race program transport setup should be held to."

A transport setup built around high-end bikes deserves the same attention to detail at the hitch receiver as it does at every other point in the system. The RockyMounts Anti-Wobble Block Assembly for SplitRail and BackStage addresses the one variable that undermines an otherwise dialed rack, integrating a 3/4in ball bearing directly into the hitch tube to eliminate the lateral movement and receiver slop that translate into noise, wear, and instability at highway speeds with a loaded rack. High-strength steel construction with a corrosion-resistant finish ensures the assembly maintains its fit and function through full seasons of hard use without introducing the degradation that cheaper solutions develop over time.

Compatible exclusively with 2in hitch receivers and designed specifically for SplitRail and BackStage rack geometry, the fit is precise by design rather than approximate by necessity. Two M6 screws complete the installation in minutes and lock the entire assembly into a configuration that behaves as a single integrated unit rather than a rack negotiating clearance with a receiver. For riders and programs where every component in the chain is held to a performance standard, this assembly closes the last gap in a transport setup that should have been this solid from the start.
